摘要:

我们报告的详细蒙特卡罗模拟的结果,预计在气球高度和可能的卫星轨道的硬X射线编码孔径相机正在开发的MIRAX任务的性能。基于一个彻底的质量模型的仪器和详细的规格的光谱和角度依赖的各种相关的辐射场在平流层和轨道环境,我们使用了著名的包GEANT 4模拟仪器背景的相机。我们还显示了源场的模拟图像,以观察和计算的仪器在这两种情况下的详细灵敏度。这里报告的结果是特别重要的研究人员在这一领域考虑到,我们提供了重要的信息,不容易在文献中找到,如何准备输入文件和计算关键的仪器参数,以执行GEANT 4模拟高能天体物理学空间实验。

英文摘要:

We report the results of detailed Monte Carlo simulations of the performance expected both at balloon altitudes and at the probable satellite orbit of a hard X-ray coded-aperture camera being developed for the MIRAX mission. Based on a thorough mass model of the instrument and detailed specifications of the spectra and angular dependence of the various relevant radiation fields at both the stratospheric and orbital environments, we have used the well-known package GEANT4 to simulate the instrumental background of the camera. We also show simulated images of source fields to be observed and calculated the detailed sensitivity of the instrument in both situations. The results reported here are especially important to researchers in this field considering that we provide important information, not easily found in the literature, on how to prepare input files and calculate crucial instrumental parameters to perform GEANT4 simulations for high-energy astrophysics space experiments.
